3 E /1/Wm/ hauls #1 M LI R0664-$3 the casin broken away and shown "insection to il ustrate the lock mechanismfltherein, each end lockembodying a keeper casing 21 secured as at 22 to the outer face 6 of thetrunk body 1,. the keeper casing 21 being open at its upper end andhaving projeeting upwardly from the side walls thereof, inwardlyextending. latch lugs 23.-

. The lock casing 24 of the end lock'is secured as at 25 to the trunkcover 2 inalinement? with the keeper casing 21, the lock casing '24enclosing a pair of latch levers 26 pivotally mounted as at 27 andcarrying depending latch heads 28 projecting out- 15 casing 24 with the,latch heads 28 normally separated or spring pressed outwardly by thespring 29 engaging the latch lever 26 below the pivot point thereof.When the 9. trunk lid or cover 2 is moved to a closed position asillustrated in Fig. 1, the latch heads '28 are projected into theadjacent open end of the keeper casing 21 and automatically engage thelatch lugs 23 in the keeper casing. 3 w

The releasing means for the latch levers 26 embodies devices associatedwith the swinging beep and latch levers, a casing 0 30 secured as at 31to the inner face of 3 ,with the mountingplate 4 of the swinging 'haspoverliesj an opening 32 formed in the front wall of: said cover 'A' pairof bell crank levers 33 is pivotally' supported within the casing'30,the corresponding leg 34 of each bell crank: lever normally traversing'the wall opening 32 as shown in-Fig.'2 while ;the other leg 35 of eachbell crank lever has a relatively long linkconnection -36, that extendsthrough a side opening 37. in the casing 30 with the cam lever 38pivotally "mounted as at 39 within each end lock casing 24. theconnection between the outer ends of the links 36 and the cam 1evers38hroug'h the slotted opening 41 in the front -w'all of the cover section.The cam lever 38 includes a double cam portion 42 disposed between theupper ends of the latch levers 26fto efiect simultaneous 0p- Wardly ofthelower open end of the lock the forward side of the trunk cover 2alined eluding a pin slidably projected oration thereof. The swinginghasp' 6 carries a finger extension 43 disposed within the mounting plate4 when the hasp is in a closed position, the finger 43 being projectedthrough the opening 32 in the front wall of the cover when the hasp 6 isswlung upwardly as illustrated in Fig. 5 with the free end of the fingerl3 engagin tl1elegs 34- of the bell crank levers 33 or shifting the bellcrank levers and links 36 for operating the cam lever 38. It willtherefore be seen that when the hasp '6 is elevated after being releasedfrom the keeper plate 8, the end locks are automatically releasedand thetrunk cover 2 maybe shifted to an open position.

While there is herein shown and described the preferred embodiment ofthe present invention, it is nevertheless to be understood that minorchanges may be made therein withoutdeparting from the spirit and scopeof the invention'asclaimed.

hat is claimed is new is 1. In a trunk lock, a key-operated swinginghasp, end locks including tensioned latch levers and rigid keeper lugsfor the latch levers, and means for disengaging the latch levers fromthe lugs arranged in the path of movement of the hasp.

2. In a trunk lock, a key-operated swinging ha'sp, end locks includingtensioned latch ,levers and keeper lugs for the latch levers a fingerextension carried by the hasp and link and lever mechanism interposedbetween the latch levers and swinging hasp adapted to be operated'by thefinger extension on the hasp.

3. In a trunk look, a swinging hasp, end locks including t'ensionedlatch levers and keeper lugs for the latch levers, a hngcr extensioncarried by'the swinging hasp. a

lever-cam pivoted between the-latch levers,

bell-cranks pivoted adjacent the hasp and link connections between thelever-cams and beILcranks with one leg of each bell-crank arranged inthe path of movement of the hasp finger.

In testimony whereof I affix my signature.
